Pyrite Wikipedia

Pyrite's metallic luster and pale brass-yellow hue give it a superficial resemblance to gold, hence the well-known nickname of fool's gold.The color has also led to the nicknames brass, brazzle, and Brazil, primarily used to refer to pyrite found in coal.. The name pyrite is derived from the Greek πυρίτης λίθος (pyritēs lithos), "stone or mineral which strikes fire", in turn from

Pyrite an overview ScienceDirect Topics

Pyrite (FeS 2) is commonly associated with other valuable metal sulfides, and with precious metals. In particular, some gold ore deposits contain the gold as particles embedded in grains of pyrite. In order to leach the gold, the pyrite must be roasted under controlled temperature and pO 2, such that only hematite (Fe 2 O 3) is present in the
